		[code]Boa noite.
Andei pesquisando e não achei nenhuma calculadora com interface programada em Python, todas era pelo terminal.
Então tentei criar uma kkkkk
Mas sou novo em programação..
A interface da calculadora está pronta, mas não consigo somar,subtrair,mutiplicar ou dividir dois numeros diferentes.
Eu só consegui fazer o seguinte..
Se eu clico, por exemplo, no 2 e clico em + "somar" ele vai somar 2. Se eu clico no 8 e depois no + ele soma mais 8. E assim respectivamente para cada operador matemático.
Alguem pode me ajudar?
Segue o algoritmo:
